Window Regulator plastic clip backing nut part #

[nra0707]

I'm having trouble determining what the part number is for the backing nut that holds the bolt and plastic clip together onto the window glass and regulator. I noticed when changing the plastic clips last fall that I was missing one backing nut...and didn't find it at the bottom of the door interior.

I can't really tell from RealOEM.com. I remember the backing nut having the shape of a flat conical cylinder and not in the traditional hex or octagonal nut. Any help? Thanks.
